OnBook's primary audience is service professionals and businesses that rely on appointment-based work. This includes beauty salons, clinics, consultants, personal trainers, therapists, dentists, fitness studios, and similar service providers. The platform is ideal for solo practitioners who want to automate their scheduling, as well as teams with multiple professionals who need individual schedules and centralized management. OnBook is particularly well-suited for professionals in Brazil and English-speaking markets, as it supports both Portuguese (BR) and English languages.

OnBook was created by TeddyLabs in 2025 with the vision of building a modern, complete appointment scheduling platform for service professionals. The founders noticed that many existing solutions were either too complex and expensive, or too simple and limited. OnBook was built to fill that gap — offering a powerful yet easy-to-use platform that covers everything from scheduling and client management to payments and analytics. Starting as an MVP, it has grown to serve over 700 professionals with more than 50,000 appointments booked, while maintaining a strong focus on user experience and reliability with 99.9% uptime.
